As already mentioned the engine and transmission in the car was replaced in 2004, but I still have the original, freshly rebuilt straight eight flathead engine and the 3 speed transmission .  The car has a wheel base of 119".  Hudson broke it down into two chassis models for 1930.  Model U and Model T.   The T had a 119" wheel base and the U had a 126" wheel base.  There were 7 models in the 119" length car.  My car was called the Standard Sedan. There was also a Touring Sedan, and as best as I can tell the only significant difference was that the Standard Sedan had  a roof drip rail that ended at the back edge of the third side window as mine does.  Whereas the Touring Sedan drip rail continues a little further and then turned down and followed the rear edge of the third window frame. 
The second difference is that the third windows on my car are set very far back so there is only a couple inches of body steel before it rounds the curve to the back of the car.  The Touring Sedan has about 8 inches past the third windows. 
Another difference is that my car has one spare wheel mounted recessed into the front right fender and the Touring Sedan had a spare mounted in both front fender. However I believe that two fender mounted spares were an option for the Standard Sedan.  Wire wheels were also an option.
